Answer : The limiting reactant is 
Explanation : Given,
Mass of 
= 30.0 g
Mass of = 75.0 g
Molar mass of = 44 g/mole
Molar mass of = 32 g/mole
First we have to calculate the moles of and .
Now we have to calculate the limiting and excess reagent.
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 5 mole of react with 1 mole of
So, 2.34 moles of react with 
moles of
From this we conclude that, is an excess reagent because the given moles are greater than the required moles and is a limiting reagent and it limits the formation of product.
Therefore, the limiting reactant is
False. At equilibrium, the rate of forward reaction is equal to the rate of backward reaction. The net concentration of both products and reactants won't change, but the reactions still take place.
Unit of M is also mole/L, where mole is the moles of solute and L is the volume of the solution. The latter is given: 158 mL or 0.158 L. So we need to find out the moles of NH4Br.
Moles of NH4Br = Mass of NH4Br/molar mass of NH4Br = 17.0g/(14+1*4+79.9)g/mol = 0.1736 mole.
So, the molarity of the solution = 0.1736mole/0.158L = 1.10 mole/L = 1.10 M
Hydrophilic molecules that are to be released by cells are stored in membrane-bound structures called <u>Secretory vesicles.</u>
<u></u>
The head, which forms the outer and inner lining, is 'hydrophilic' (water-loving), while the tail facing the interior of the cell membrane is 'hydrophobic' (water-hating).
All lipid molecules in cell membranes are amphiphilic (or amphipathic). That is, they have a hydrophilic (“water-loving”) or polar end and a hydrophobic (“hydrophobic”) or non-polar end.
Cells contain membrane-bound structures called cellular organelles and more complex chemicals. Organelles are sometimes referred to as subunits within cells designed to perform specific functions.
Channel-forming proteins can be used to facilitate the transport of water and other hydrophilic molecules. These channels are often gated to regulate transport rates. In facilitated transport, a hydrophilic molecule binds to a 'carrier' protein. This is a form of passive transport.
